What happened?

Description

If you put the @deprecated directive on a mandatory field, cosmo builds the schema even though it shouldn't before the field is made optional (for schema compatibility)

apollo – GraphQLError: Required input field TestInput.testField cannot be deprecated. graphql-schema-linter – Required input field TestInput.testField cannot be deprecated. (invalid-graphql-schema) cosmo – OK, composite schema!

Steps to Reproduce

Initial scheme

input TestInput {
    testField: String!
}

Set the directive and expect an error during composition

input TestInput {
    testField: String! @deprecated
}

Cosmo doesn't cotton on to composition errors
